[0002] The warehouse management system based on radio frequency identification RFID (abbreviation of Radio Frequency Identification) introduces RFID technology into the existing warehouse management. Its principle is to conduct non-contact data communication between the reader and the tag to achieve the purpose of identifying the target. Automated data collection is carried out for each operation link such as warehouse arrival inspection, warehousing, outbound, transfer, transfer, inventory counting, etc., to ensure the speed and accuracy of data input in each link of warehouse management, to ensure that the enterprise timely and accurately grasps the real data of inventory, and reasonably maintains and controls the enterprise inventory. Through scientific coding, it is also convenient to manage the batches and shelf life of items. Using the system's storage location management function, the current location of all inventory materials can be grasped in a timely manner, which is conducive to improving the work efficiency of warehouse management.

[0003] The packaging box on the surface of the goods will be affixed with an RFID electronic tag, which can record the information of the goods when passing through the identification device with an RFID reader. The existing identification device is installed on a conveyor belt. When the goods are put into the warehouse, they are transferred through the conveyor belt. Workers or robots move the goods to the conveyor belt and position the side with the RFID electronic tag at an approximate angle. When the goods pass through the identification device, the camera marks the content of the RFID electronic tag. If the goods are placed at too large an angle or the conveyor belt is transported at too high a speed, the goods will be transferred without being identified.

[0004] Therefore, the utility model mainly improves the structure of the cargo identification device and provides an interception function, which can make the cargo stay briefly in the scanning area, thereby facilitating high-accuracy identification of the cargo. Utility Model Content

[0021] The single-side vertical beam 2 has a cylinder assembly 5 that drives the corresponding side cantilever 4 to flip up and down. The output end of the cylinder assembly 5 is driven and matched with the cantilever 4 through a connecting rod 51. The cylinder assembly is a horizontal installation structure, and the output end drives the entire cantilever to flip through the connecting rod, thereby controlling the up and down displacement of the interception rod. Both ends of the connecting rod are hinged with the corresponding cylinder assembly and cantilever.

[0022] The single-side vertical beam 2 is also equipped with an RFID reading and writing camera 11. It has a built-in RFID reader / writer, a data recording system, etc.
